The microstructure evolution of Ti-43Al-6Nb-1Mo-1Cr alloys during multi steps forging process: (a) The as-cast microstructure; (b) The forged microstructure after the first step forging process; (c) The forged microstructure after the second step forging process; (d) The as-cast microstructure during insulation process before forged; (e) The DRXed grains nucleation and (α2 + γ) lamellae deformation during the first step forging process; (f) The DRXed grains growth during process annealing; (g) The DRXed grains and (α2 + γ) lamellae broken during the second step forging process.
